Abstract

A global positioning system (GPS) device including an antenna and a baseband unit is disclosed. The antenna receives a wireless signal group. The baseband unit processes the wireless signal group to generate a position signal. The position signal is updated every time interval. The duration of the time interval is changed dynamically.

1. A global positioning system (GPS) device, comprising:
 an antenna receiving a wireless signal group from at least two satellites; and 
 a baseband unit processing the wireless signal group to generate a position signal, wherein the position signal is updated every time interval, and the duration of the time interval is changed dynamically according to at least one of: 
 a remaining capacity of a power source of the GPS device, 
 a number of the satellites, and 
 a movement path of the GPS device. 
 
     
     
       2. The GPS device as claimed in  claim 1 , wherein the duration of the time interval is reduced when the remaining capacity of the battery exceeds a preset value. 
     
     
       3. The GPS device as claimed in  claim 1 , wherein the duration of the time interval is reduced when the number of the satellites exceeds a preset value. 
     
     
       4. A method for a global positioning system (GPS) device, comprising:
 receiving a wireless signal group from at least two satellites; 
 processing the wireless signal group to generate a position signal; and 
 updating the position signal every time interval, wherein the duration of the time interval is changed dynamically according to at least one of: 
 a remaining capacity of a power source of the GPS device, 
 a number of the satellites, and 
 a movement path of the GPS device. 
 
     
     
       5. The method as claimed in  claim 4 , wherein the duration of the time interval is reduced when the remaining capacity of the battery exceeds a preset value. 
     
     
       6. The method as claimed in  claim 4 , wherein the duration of the time interval is reduced when the number of the satellites exceeds a preset value. 
     
     
       7. The method as claimed in  claim 4 , wherein the duration of the time interval is reduced when the GPS device moves in a single direction. 
     
     
       8. The GPS device as claimed in  claim 1 , wherein the duration of the time interval is reduced when the GPS device moves in a single direction. 
     
     
       9. A baseband unit of a global positioning system (GPS) device with an antenna receiving a wireless signal group from at least two satellites, said baseband unit processing the wireless signal group to generate a position signal, wherein the position signal is updated every time interval, and the duration of the time interval is changed dynamically according to at least one of:
 a remaining capacity of a power source of the GPS device, 
 a number of the satellites, and 
 a movement path of the GPS device.
